The CW will bid farewell to “Gossip Girl” on Dec. 17 with a two-hour series finale.

The final episode will include a look back at memorable moments from the show’s six-season run. Included will be a sneak peek of the net’s midseason newbie “The Carrie Diaries,” one of the latest ventures from “Gossip Girl” creators Stephanie Savage and Josh Schwartz.

“Gossip Girl,” which is produced by Warner Bros. Television, was one of the CW’s top-rated shows when it began in 2007, drawing 3 million for several episodes of that first season. However, viewership decreased as the skein chugged into its fifth season and beyond, with the current and final season bowing to less than 800,000 total viewers on Oct. 8.

The CW staved off the preem of “Carrie Diaries” until midseason in order to focus marketing efforts and aud attention on a thorough sendoff for “Gossip Girl.”
